Is a supervisor liable for failing to act on a report of an unconstitutional act by a subordinate that resulted in injuries to an inmate?

In Starr v. Bacca, 652 F.3d at 1208-1212, the court found supervisor liability when numerous unconstitutional acts by subordinates resulted in injuries to inmates and these acts were reported to the supervisor, providing him with notice of the acts. The supervisor's failure to ameliorate the problems while in possession of facts that amounted to an inference of substantial risk was reckless or callous indifference to the rights of inmates and was sufficient to state a claim of supervisory liability for deliberate indifference. Id. at 1208.
